Usage Guidelines

After DHCP snooping is enabled, the device generates a DHCP snooping binding table by listening to DHCP Request messages and Reply messages. A binding entry contains the MAC address, IP address, number of the interface connected to the DHCP client, and VLAN ID. You can run the display dhcpv6 snooping user-bind command to view the DHCPv6 snooping binding table.

Example

# Display the DHCPv6 binding table.
